DOOR-CATCH.

Specification of Letters Patent.

Patented Aug. 25, 1908.

Application filed November 14, 1907. Serial No. 402,096.

To all whom it may concern:

Be it known that I, PETER Form, a citizen of the United States, residingin Somerville, in the county of Middlesex and State of Massachusetts,have invented an Improvement in Door-Catches, of which the followingdescription, in connection with the accompanying drawings, is aspecification, like letters on the drawings representing like parts.

This invention relates to a fastening device for doors and has for itsobject to provide a simple, cheap and efficient device, which isespecially designed and adapted for use on doors of sinks, closets, etc.

The invention has for one of its objects to provide a door-catch orfastening device, which automatically compensates for shrinkage of thedoor away from its casing.

Another feature of the invention consists in providing a novel strikerwith which the bolt cooperates and which can be applied tothe door witha minimum amount of labor and expense.

These and other features of this invention will be pointed out in theclaims at the end of this specification.

Figure 1 represents in elevation a door and its casing provided with afastening device embodying this invention. Fig. 2, an elevation with thedoor opened. Fig. 3, a crosssection on the line 33, Fig. 1. Fig. 4, a detail in section to be referred to. Fig. 5, a detail in elevation andsection on an enlarged scale of the catch shown in Fig. 1. Fig. 5 a rearelevation of the catch shown in Fig. 5. Fig. 6, enlarged details of thestriker shown in Fig. 2. Fig. 7, a section on the line 77, Fig. 6. whichthe catch is made, and Fig. 9, a partial section and elevation to bereferred to.

Referring to the drawing, it represents the casing of a sink, closet orsimilar structure, which is provided with a door I), hung upon hinges cand adapted to be held in its closed position by a fastening deviceembodying this invention.

The fastening device comprises a catch shown separately in Figs. 5 and 5and a striker shown separately in Fig. 6. The catch comprises a shell (1closed at its rear end by a head 6 and open at its front end for thereception of a bolt f which is preferably made of sheet metal, such assheet brass, and consists of a cylindrical body portion 10,havingarounded substantially conical nose or end l2 and reaiwardly extendedarms 13, 14,

Fig. 8, a plan of the blank from' preferably substantially diametricallyopposite and extended rearwardly through slots 16, 17, in the head e ofthe shell, the said arms being bent at their ends to form fingers 20,which serve as stops to limit the outward movement of the bolt f, underthe influence of a helical spring 21 located within the shell cl andbolt f, and bearing against the nose or front end 12 of the bolt andagainst the head 6 of the shell. The bolt f may be made in one piecefrom a blank shown in Fig. 8, which consists of a disk 24 having thediametrically opposite arms 13, 1.4. The disk 24 is struck up or forcedby suitable tools (not shown) to form the bolt shown in Fig. 9, which isthen inserted into the open end of the shell (Z over the spring 21, thearms 13, 14 passing through the slots 16, 17, and being then bent toform the fingers 20.

It will be seen from an inspection of Fig. 5,

that the boltf is capable of being forced back into its shell (Z againstthe action of the spring 21, and that when the pressure is removed, thespring forces the bolt outward until arrested by the engagement of thefingers 20 with the head a. It will thus be seen, that when the bolt isapplied to a door or as in the present instance to the door casing, thebolt automatically compensates for shrinkage of the door or casing.

When first applied to the casing, the door usually fits snugly asrepresented in Figs. 1 and 3, but in time the wood shrinks and aconsiderable space is left between the door and its casing asrepresented in Fig. 4. In this case the boltf is forced outward from itsshell and is kept in engagement with its striker, which may be andpreferably is made as herein shown, and consists of a sheet metal platebent to form two members 30, 31, sub stantially at right angles to eachother. The member 30 is provided with a concavity 32 for the receptionof the nose 12 of the bolt f and both members at their junction may beprovided with a depressed portion 33, which forms an inclined reinforceor brace for both members, thereby enabling a strong and rigid strikerto be made from substantially thin sheet metal stock. The members of thestriker are provided with suitable holes 35 for the reception of nails,brads or screws 36 by which the striker is secured to the door. Byreference to Figs. 3 and 7, it will be seen that the striker may besecured to the door in a minimum time, as it is only necessary to cutout with a chisel or other tool, a rough recess in the edge of the door.It is not necessary that the recess 40 be nicely made as the strikerdoes not require to be nicely fitted therein. both of sheet metal may bemade at a mini mum expense and said parts may be assembled and connectedtogether by simply bending the arms 13,14, to form the fingers 20,

which requires the least possible time and labor. The shell (Z may andpreferably Will be provided with a flange 41 to abut against the casinga and position the catch in the casmg.

Claims.

1. In a fastening device of the character described, in combination, ashell provided at one end with a head having a slot or opening, a boltmovable in said shell and provided with an arm extended. through saidslot, a spring within the shell acting to force the bolt out therefrom,and means on the said arm outside of said shell to engage the head. ofthe latter and limit the outward movement of said bolt by said spring.

2. In .a fastening device of the character described, a sheet metalstriker comprising two members substantially at right angles to eachother, one of said members having a concavity to form a socket for abolt, and both of said members having a depressed The shell d and thebolt f being portion forming an inclined brace or reinforce for bothmembers, substantially as described.

3. In a fastening device of the character described, a shell, a boltmovable longitudinally therein, a spring in said shell to move the boltin one direction, and means located outside of said shell and connectedwith the bolt within the shell to limit the movement of the bolt by saidspring, substantially as described.

4. In a fastening device of the character described, a shell provided atone end with a head. having slots and open at its other end, a sheetmetal bolt movable in said shell and comprising a cylindrical bodyportion having a rounded nose and arms extended rear- Wardly through theslots in said head, said arms being bent outside of said shell to formfingers, and a spring within the shell to normally force the boltoutward, substantially as described.

In testimony whereof, I have signed my name to this specification in thepresence of two subscribing Witnesses.
